Problem 1. Water flows between two reservoirs through a 4,000-ft pipeline constructed of ductile iron (f= 0.019) as shown below. The pipeline low point is 125.0 ft. a. Determine the flow between reservoirs when only an entrance loss (Ke = 0.5) and exit loss occur. b. Calculate the pressure at the midpoint with centerline elevation 125.0 ft. c. Draw the energy and hydraulic grade lines. 255.0 ft 8 inch 2000 ft 8 inch 2000 ft 125.0 ft 140.0 ft

8. A pumped fluid distribution system is being designed to deliver 400 gal/min of water to a cooling system in a power generation plant. Use the figure below to make an initial selection of Schedule 40 pipe sizes for the suction and discharge lines for the system. Also, solve for the actual average velocity of flow for each pipe. DN (mm) NPS (in) 250 200 150 - 125 - Suction lines 100 - 90 - 3 65 - 2 50 Discharge lines 40 32E 25 E 15 20 200 400 600 800 1000 2000 4000 6000 8000 10000 10 100 Volume Flow Rate, Q (gal/min) 6 8 10 ++++ 15 20 25 30 40 +++++++++ ++++++++++++ 60 80 100 150 200 300 400 500600 800 1000 1200 2000 Volume Flow Rate, Q (m/h)

Answer the following:  a.) What is the velocity inside the pipe? b.) Compute for the Reynolds number
